The results show that the effects of pressure on tautomeric equilibrium constant K〓 is very limited at pressures much higher than the phase separation pressures, while the K〓 increases sharply as the pressure approaches the critical pressure or the bubble point pressure of the mixed solvents.

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.

On the safe side, we should use active soil pressure and passive soil pressure to calculate the support strength before T increased. That is RA=EA-EP Among them: RA ………… holding strength EA ………… composite force of active soil pressure EP ………… composite force of passive soil pressure Immediately, flexural torque distribution of enclosure wall can be counted. Mmax is the location of shear force zero. Equivalence beam method abridges. No matter which kind of supporting structure form, the key problem lies in the establishment depth of catch point, severity of support and enclosure wall, penetration depth and pit bottom quality of soil property.

Through field measurement for the contact pressure of box foundation with Ⅰ shaped plane of a high rise building on cobble subsoil, the distribution law of the contact pressure has been diagrammed. At the same time, the contact pressure has been calculated with finite compression layer model, which is well accordant with the measured result. The relative error of average value for the measured to the calculated contact pressure is 6.9%. This shows that the numerical calculation is right.

Lithologies are mostly sand and carbonate rocks, caps are mud rock, shale and magmatite. Entrap types are anticline, fault block rebuilt by breaking and the screened entrap diapered rock mass. The composition is CO_2, N_2, CH_4, C_2H_6 and He etc. It is magma air source body and its geologic fashions are intrusion and buried volcanic conduit. The relations between gas reservoirs and gas source bodies have three types: magma intrusion-breaking-communicated gas reservoir, magma intrusion-contacted CO_2 reservoir and buried volcanic conduit-contacted gas reservoir. The CO_2 migration in magma intrusion is consisted of fusing and crystallizing phases;it in volcanic conduit is consisted of near-surface effusion and crystallizing phases.The buoyancy of CO_2 in water far more than migration resistance in breaking or chink, CO_2 is easy float upward, the floating can results in differentiation of different density gases and concentration of sealed gas. The gas in sand reservoir firstly migrate into the higher porosity and coefficient of permeability sand, and along with the pressure going up it migrate into the lower. In magma intrusion-breaking-reservoir migration, CO_2 firstly migrate into watered breaking, began gravity differentiation and concentrate, the gas pressure time and again go up, CO_2 migrate into reservoir and concentrate under expansibility as the pressure reach upward a given extend. The CO_2 in reservoir experience four breaking modes: chemistry deposition, dissolution, diffusion and mechanic breaking, the pressure balance can be broken by faulting and the CO_2 will further migrate and form new reservoir.
