Volcanic Gas Reservoir In The Well Network Deployment Method Research

Deepens and the volcanic rock reservoir unceasing discovery along with the oil gas exploration degree, the volcanic rock reservoir takes the oil gas exploration the new domain and has aroused the petroleum scholars attention and the interest. In order to make up for the influence on the oil output reduces, the Daqing Oil Field increases the gas probing development dynamics. It has obtained the significant breakthrough to the pine distant basin in-depth volcanic rock reservoir exploration. ShengPing natural gas field is at present the most fire precipice gas pool in the Daqing Oil Field discovery. Till 2004, in the ShengPing area camp city group, ascends Low Kuzu and the source group submits verifies the natural gas geological reserve 194.77×10~8 m~3 , gas-bearing area 32.5 km~2 , minable reserve 159.9×10~8m~3。 Therefore, the highly effective rational development ShengPing natural gas field not only has the vital significance to the Daqing Oil Field development, Moreover deepens to our country gas probing development domain has the profound influence.In the research process of later date develops the well pattern deployment way in this to the ShengPing natural gas field, Uses the matter balance, the well test analysis, the economic evaluation, the value simulation method later period produces the reasonable output, the production differential pressure, the development formation, the well placement basis and the well pattern density size, the reasonable well pattern pattern to the natural gas field and so on conducts the thorough research, and has obtained some important understanding:1. Uses the yielding material balance method and the unstable well test law calculates the single well control reserves, Rises the deep 1 well, rises the deep 2 wells, rises the deep 2-1 well single well control reserves respectively is 5.21×10~8m~3,26.13×10~8m~3 and 10.43× 10~8m~3。2. Has carried on processing to the ShengPing natural gas field all well performance testing material, and used the many kinds of methods to produce to the ShengPing natural gas field can carry on the correlation -like connection return. Firstly established for the first time has suited a Thangbinh volcanic rock natural gas field law to produce can the formula;3. The research has analyzed the gas well reasonable production differential pressure and the reasonable output, Proposed for the first time is mad the day in view of the volcanic rock when the proration production, the research analyzed had been mad the reasonable production differential pressure might take the static formation pressure 10%～15%,The reasonable output takes the unimpeded current capacity 1/3～1/5; Uses the new model, Proved the ShengPing natural gas field gas well to take along the fluid ability, The ShengPing natural gas field major part gas well the intermediate stage cannot accumulate the fluid in the beginning of the production.4. From economic evaluation, gas engineering and simulation angle computation ShengPing natural gas field reasonable well pattern density, the interwell distance in wellblock of the...
