Description
Technical field
The utility model relates to a kind of self-priming device that is used for the spontaneous imbibition displacement of reservoir oil.
Background technology
The self-priming instrument is widely used in spontaneous imbibition displacement of reservoir oil research, is one of major equipment in this research.The self-priming instrument that is used for the spontaneous imbibition displacement of reservoir oil also claims " water absorption meter ", conventional self-priming instrument synoptic diagram can be with reference to " reservoir physics " (He Gengsheng, 1994, first published, P190～191) and SPE36688 (article name: OilRecovery in Fractured Oil Reservoirs by LowIFT Imbibition Process.Author: Al-Lawati S. and Saleh S).The structural representation of conventional self-priming instrument is seen Fig. 1, Fig. 2 and Fig. 3, narrates the major defect that they exist separately below respectively:
Conventional self-priming instrument as shown in Figure 1 is divided into self-priming instrument main body 1 and 2 two parts of base, up and down by the realization that is threaded, the major defect that it exists comprises: 1) install inconvenient, in case self-priming instrument main body 1 and base 2 occur poorly sealed, leakage takes place behind the solution that adds the imbibition use easily, influences whole research process; 2) rock core position in the self-priming instrument is difficult to fix, in case the self-priming instrument rocks slightly, vertically the rock core of placing is toppled over easily or contacted with the sidewall of self-priming instrument main body 1 part, thereby influences experimental observation.
Conventional self-priming instrument as shown in Figure 2 is divided into two parts of measurement section 3 (being positioned at self-priming instrument top) and core chamber 4 (being positioned at self-priming instrument bottom), partly reach the purpose (similar) of sealing self-priming instrument internal liquid between them with the glass wares of band ground by ground, the major defect that it exists comprises: 1) core chamber 4 of self-priming instrument is for flat, after rock core is put into, the rock core bottom surface directly contacts with core chamber 4 bottoms, thereby make imbibition be subjected to very big influence, the imbibition situation that also is unfavorable for observing the bottom surface simultaneously; 2) rock core position in the self-priming instrument is difficult to fix, in case the self-priming instrument rocks slightly, vertically the rock core of placing is toppled over easily or contacted with the sidewall of self-priming instrument core chamber 4.
As Fig. 3, conventional self-priming instrument shown in 4 is the modified on the basis of conventional self-priming instrument as shown in Figure 2, it also is divided into two parts of measurement section 3 (self-priming instrument top) and core chamber 4 (self-priming instrument bottom), between measurement section 3 and core chamber 4, be provided with the neck 6 of contraction, measurement section 3 and core chamber 4 partly reach the purpose of sealing self-priming instrument internal liquid by the ground of neck 6, core chamber 4 middle parts are three supporting legs 5 that are used to support rock core of distribution evenly, the major defect that it exists comprises: 1) directly be placed on above three supporting legs 5 of core chamber 4 owing to rock core, the rock core position is affected easily when the self-priming instrument is installed, and occurs rollover or inclination when especially rock core is vertically placed easily; 2) rock core position in the self-priming instrument is difficult to fix, in case the self-priming instrument rocks slightly, vertically the rock core of placing is toppled over easily or is contacted with the sidewall of self-priming instrument core chamber 4, rock core also may occur from falling at the bottom of 4 glasss of the core chamber between the supporting leg 5 or being blocked by supporting leg 5, influences the observation experiment process.And the core chamber 4 of self-priming instrument is flat, and in a single day rock core is fallen at the bottom of 4 glasss of the core chamber, and the rock core bottom surface directly contacts with core chamber 4 bottoms, can make imbibition be subjected to very big influence, the imbibition situation that the while also is unfavorable for observing the bottom surface; 3) because there is a neck 6 that shrinks in the core chamber 4 of self-priming instrument, in the incipient stage of experiment, fuel-displaced this neck 6 that is collected at easily of rock core imbibition, thereby the accurate metering of influence oil.
