Feasibility Study Of Horizontal Well Development Of Su54Block

In recent years， the development process of sulige gas ifeld has been carried out somepreliminary gas reservoir geological studies, seismic evaluation? dynamic analysis，capacity evaluation arid other research work.But as technology advances*it is need to deepenthe Soviet Su54block of geological knowledge T feasibility of horizontal wells，horizontalwells preferred location*provide technical support to improve the success rate of drilling，development of efficient gas field.In this paper? the study area has build a gas-bearing strata line dividing contrast， theestablishment of he8r shanl stratigraphic Mount a layer segment. Meanwhile t from thereservoir rock characteristics， physical characteristics, reservoir depth and reservoirthickness*reservoir heterogeneity and reservoir pore types? pore structure characteristics ofreservoir properties and other aspects are researched: On this basis， according to the Gasproduction test results and the results of dynamic analysis， research in the study area toidentify gas and water standards*the single well gas， water layer identification^conductcomparative work aspect of the aqueous layer r through the implementation of various typesof water body boundaries*extending the range of flat track Shui body Analysis of the mainlayer formation water distribution.Combined with geological reseacrh that Su54horizontal wells in the block deploymentfavorable overall structure ts very flat area， there are a small number of developed nosestructure: the effective gas reservoir is developed? and it is equal to the thickness of greaterthan6m: longitudinally continuous development of effective sand， stable distribution； themain gas reservoir mudstone interlayer thickness smaller; higher deployment of horizontalwells adjacent vertical wells yield favorable areas， small water production， productionstability. Favorable area of the geological conditions arc met the requirements to deployhorizontal wells.
