Description

Measurement and adjustment linkage system and its operation process

Technical field

The invention relates to the field of oilfield layered water injection technology, in particular to a measurement and adjustment linkage system and an operation process thereof.

Background technique

There are many methods for stratified water injection in oil fields, such as oil and casing layered water injection, single-tube layered water injection, and multi-tube layered water injection. However, single-tube layered water injection pipe columns are most common. Single-layer stratified water injection is the only one of the pipe columns in the well. The packer is used to seal the entire injection well section into a plurality of non-intersecting intervals, each of which is equipped with a water distributor. The injected water enters the well from the oil pipe and is injected into the formation of each interval by the nozzle control on each layer of the water distributor. According to the water distribution structure, it can be divided into fixed water distribution pipe column, movable water distribution pipe column and eccentric water distribution pipe column.

Although the eccentric distribution pipe column has made greater progress than the fixed and hollow type, and has a large proportion in the oilfield water injection, it still has a series of shortcomings. The device for regulating the flow rate in the eccentric water distributor is called a plugging device, and the essence thereof is a throttling device. Before the packer is set, the plugging device that goes down to the bottom of the well with the water distributor is installed with a dead water nozzle. After the ball is pressed and set, the plugging device is taken out by the wellhead into the fishing device, and the grounding is required according to the dispensing requirements. Derived from the empirical formula, calculate the required faucet diameter, replace the dead water nozzle, and then use the fishing device into the water distribution cylinder. After all the plugs of the interval are replaced with fixed nozzles, the test equipment is placed, and the water injection test is performed for each layer. Due to the complicated working conditions in the underground, it is difficult to calculate the actual flow rate of the fixed nozzle to the underground through simple calculation and derivation, so it is necessary to test and measure again and again. This kind of traditional plugging device has a large amount of work when it is dispensed with water. Even a single-layer deployment often requires multiple fishing operations, and it takes two or three days or more to complete. Not only are workers labor-intensive, but also inefficient, which limits the productivity of oil fields. The multi-layer water injection, the workload and difficulty are multiplied. Since the fixed nozzle can not be adjusted steplessly, the flow rate of the final deployment is still different from the flow required by the design. Taking Shengli Oilfield as an example, the entire oilfield is divided into 1425 water distribution horizons, and the qualified interval is 1034. The pass rate is only 72.56%. For the qualified concept, the control water distribution error is ±10%, and the accuracy is not high.
