The work summary network publishes the supervision summary of underground work for free. For more information about underground work supervision and summary, please visit the work summary network. I have been working as a technician for 20xx years, and I have earnestly performed my duties as a technician, worked conscientiously and responsibly, actively absorbed good working methods, mastered new underground construction technologies, enriched workover knowledge, and improved my ability to solve problems. Over the past year, under the correct leadership of leaders at all levels in the company, I have been able to study and perform the duties of this position seriously, work conscientiously and responsibly, and can better complete the tasks assigned by the organization. I summarize the technical work in 20xx years as follows:

First, do a good job in the daily management of our workover operation.

1. At the same time, we should be strict with ourselves in our work, urge and require all construction teams to carefully prepare all workover data, strictly control the construction quality of working procedures, put an end to passive operations, and improve the efficiency of workover operations. Prepare the completion summary and report the construction data in time. Through my work in recent years, I have deeply realized the importance of quality work in workover operations.

2. In view of the employees' weak knowledge of workover technology, targeted technical training is provided. Combined with the actual situation of our team, we will focus on training employees' practical operation ability and explaining the knowledge of safety prevention and construction risk identification. It meets the needs of safety and skill operation of construction personnel. Conduct skill education for employees by means of one question per well, one lesson per week and one exam per month; Through technical knowledge learning and on-the-job training, the technical quality and practical skills of all employees, especially foreign employees, have been greatly improved.

3. While doing a good job, actively cooperate with the team leader to do a good job in safety and environmental protection of the team, collect construction information in time, arrange the operation of personnel and vehicles reasonably, and ensure the continuous workover operation.

Second, carefully prepare the construction technology and technical measures

Conduct joint review on the engineering design of the construction survey well, make clear the construction data, tasks, objectives and possible risk factors of the construction well, and determine the corresponding technical and safety schemes according to the well conditions and operation tasks. Such as high pressure wells, high oil and gas wells and high risk wells. It is necessary to formulate blowout prevention, gas prevention and other technologies and safety schemes suitable for well conditions. Especially for complex wells (such as casing broken wells, sand stuck wells, casing string wells, abandoned wells, etc.). ), in addition to serious measures for joint review, but also on-site command and supervision, so as to achieve meticulous organization and careful construction, and successfully completed the construction work:

Three, study hard all kinds of technical and management knowledge, do a good job.

In view of the double-engine operation of Xi Shi team in the underground bidding at the beginning of this year, as I am in charge of the overall technical work, I have earnestly completed the work arranged by the superior leaders and team leaders. When encountering the construction operation of complex new technology wells, I strictly organize the construction and coordination at the site.

According to the process standards, the librarians should be strictly educated in data collection and training, strictly controlled in quality, strictly implemented in the operation of the four systems, improved in operation quality, and trained in safety, well control and quality, and supervised and inspected. Cooperate with the team leader to do a good job in the construction site and strive to improve their professional level. I make full use of my spare time to learn all kinds of complex well process design and workover projects, and seize the time to learn professional business knowledge and computer knowledge to improve my professional and technical level. Strive to complete the writing of QC papers and technical papers this year. In the continuous study and exercise, I strive to improve my technical theory level, technical problem solving ability and management ability.

Fourthly, difficult and complicated well technology.

Xishi operation area belongs to a new development block. The conditions of deep wells in this block are complex, and there are wells with various technologies. Before repairing, carefully collect the well history of this well, and carefully prepare the construction design with reference to various technical standards. In the process of construction, it is strictly required to organize the construction work of various technologies on site. For example:

1. Well SH3058 (hole filling and layer modification) constructed this year: Well SH3067 in the same layer of this well has good oil recovery effect after layer modification. This layer carries out exploration and exploitation and secondary cementing in the operation area. Working procedures of this well: killing well, lifting sucker rod, releasing stuck fish, lifting pump, drifting well, washing well, lowering bridge plug, electric edge, perforating, squeezing chemicals, lowering structure, pressure test, pipe string inspection, squeezing ash, lifting structure, drilling plug, pressure test, bottom hole exploration, ground wax removal, drainage, induced injection and displacement, and completion. The construction date is from 4. And the measures for the construction personnel disclosure work. In addition to normal working procedures, we will personally adhere to shift work, strictly control the quality of each process, and conscientiously implement various process standards on site. Ensure that each process is qualified once, so that the well can complete the work safely with good quality and quantity during May Day.

2. Well 2.L3025 (water plugging by squeezing): Due to the serious water production in the current horizon of this well, the upper horizon does not produce liquid, and the water production horizon is blocked. During the construction of this well, after the pipe string test (inserting the bridge plug), it is reported to the operation area for decision, and the 700 cement truck will clean the water for 4.3m^3, then open the casing, and the tubing will try to squeeze the 3 179.5m-3 182.5m interval, with a pump pressure of 8-9MPa and a time of15min (/.

35), the displacement is 0.28 m 3/min, and there is no casing overflow (no pipe string between layers). After reporting to the production department in the operation area, decide the sealing operation. Connect a 700 cement truck, squeeze the plugging agent 8m^3 with specific gravity of 1.7g/m 3 into the tubing, and then squeeze all the plugging agent in the tubing with 9.5m^3 displacement fluid: 3 179.5m-3 182.5m interval, but when the displacement fluid is 5m^3.
