In combination with the geological features of the ga wells in West Sichuan, such as multi-payzone high pressure gradients and a large lithological change in channel sand bodies, etc., the casing cementing and perforation completion were adopted for the main well and branch holes in the well group and the interzonal pressure seals of the main well and branch holes, and the separate well fracturing and producing were all realized through a completion string with dual-tubing and dual-packer.

The principles are as follows:①preliminary interpretation is carried out on crosswell seismic data in depth domain to establish an accurate velocity model;②sinc interpolating function is used in depth-time conversion to realize waveform fidelity;③the recognition of surface seismic data is utilized to ascertain the reflection characteristics of crosswell seismic data in time domain;④ good spatial continuity of surface seismic data is adopted to retrieve the "hopper" defect in crosswell seismic profiles and the deficiency of lateral contrast between crosswell seismic data;⑤in fine calibration of well-side traces of crosswells and surface seismic data, coincident time-depth relation is used to match two seismic data so as to make the calibration more reasonable;⑥in multi-crosswell seismic data inversion by sparse spike inversion method, lateral restraints are strengthened to ensure the continuity of inversed wave impedance profile.

Theequivalence percolation resistance law is accurate enough to be used in productivitycalculation of horizontal well pattern.(3) Productivity of mixed well pattern of horizontalwell or multilateral horizontal well and vertical well is constructed and formulae are simpleenough to be used in the oilfield. The patterns include 5-spot pattern,7-spot pattern and9-spot pattern.(4) Productivity formula of united rectangular well pattern of horizontaland vertical wells is constructed. By this formula, the calculation results show that fora horizontal well length, there is a shape factor at which the productivity of the patternis biggest. So optimum method of the well pattern is proposed.(5) A new concept ofdimensionless length of horizontal well is advanced and the relationship of optimum shapefactor of the rectangular well pattern against dimensionless length of horizontal well ispresented. The influences of length of the horizontal well, area of the well pattern unitand the thickness of reservior are concerned.

According to different types of abnormal pressure,computation model for quantitative control on the abnormal pressure was set up to meet the needs of efficient and safe drilling in oil-gas fields.Some important parameters were calculated that include reasonable shut-in time,maximum flowing yield and the best flowing time of the injection wells,and reasonable bottom hole flowing pressure,extra oil production and stimulation moment of the production wells.The quantitative computational methods of them were derived.Three methods were applied to one undrilled adjustment well T1 in certain oil-gas field achieving quantitative control to the abnormal pressure in the adjustment well.

The combined production of vertical and horizontal wells can make horizontal well production rates be 2 to 5 times greater than unstimulated vertical well rates, but the areal sweep efficiency is less than that of vertical well pattern untill when the perforation ratio is greater then a certain value, which depends on the pattern of the combination. Seven spot pattern of the combination of vertical and horizontal wells has some advantages over others.
