At present, top cementing of horizontal well sieve tube technique has become one of main completion mode of Shengli Oilfield, can be applicable to bottom water reservoir.The non-average of water sandstone oil reservoir at the bottom of Shengli Oil Field is very serious, and the moisture rising of middle-late waterflooding stage is fast, and water percentage is high.How to detect water carry to put, become the primary problem solved for follow-up water-blocking operation creates conditions, therefore, carrying out the outer Production development permanent type test optical fiber of horizontal well sieve tube completion tubular is non-being necessary.
Fill-type external packer of pipe is a set of important tool in screen casing crestal waterflood bricklayer's skill work progress, and its purposes is packing annular space before cementing mainly, and the cement natural subsidence avoiding screen casing top to inject enters sieve tube segment and polluted reservoir.The transmission medium of managing outer production dynamic test is armored optical cable, optical cable is to ground downhole data transmission, just must pass through fill-type external packer of pipe, therefore, set up a set of bore hole fill-type external packer of pipe armored optical cable and pass through instrument, for the enforcement of managing the test of outer production Dynamic Optical Fiber provides strong guarantee.
Current correlation technique mainly concentrates on manages the detection of interior Production development, namely test macro is installed on the flow performance of testing tube inner fluid on oil pipe, its application concentrates on straight well zonation test or horizontal well steam injection section plane test, and to produce the application of section plane test outward also unrealized owing to lacking special instrument with the horizontal well tube that screen casing segmentation well completion matches.
Chinese patent " external packer of pipe " (patent No.: 201020570038.X) is provided with the hydraulic expanding packer of air supported head for a kind of packing element two ends, has the features such as structure is simple, reliable operation, applied range, but does not possess armored optical cable and pass through function." Self-expandable packer " (application number: 201110198657.X) for traversing pipe line is a kind of Self-expandable packer be applicable on oil pipe, and what do not reach the outer permanent type measuring techniques for optical fiber of horizontal well tube passes through requirement.
Be satisfied with bore hole fill-type external packer of pipe armored optical cable and pass through that to need to reach with construction technology supporting, technical requirement is also higher.Its difficult point is mainly manifested in the following aspects:
1. this instrument must adapt to manage outer bad hole condition, meets the annular space packing requirement under this condition;
2. due to screen casing crestal waterflood mud process matching, passage possesses sealing ability;
3. the success ratio of technique must be ensured.
Summary of the invention
