Hana ʻia ke alahaka hoʻoheheʻe me nā mea hou, i hoʻohana ʻia ma ke ʻano he mea hana hoʻokaʻawale wellbore sealing segmentation no ka haki ʻana a me ka hoʻoponopono ʻana.
Hoʻokumu nui ʻia ka plug bridge dissolvable i 3 mau ʻāpana: kino plug bridge, mechanical anchoring a me nā sila. Hana ʻia ke kino o ke alahaka me nā mea hiki ke hoʻoheheʻe ʻia me ka ikaika kiʻekiʻe, e komo pū me ka paipu waena, cone, ke apo pale a me nā hono. Hana ʻia ka mīkini heleuma i nā mea dissovable e like me ka mea lawe, a mālama ʻia ka ʻili me ka pauka alloy, nā ʻāpana alloy a i ʻole nā particle seramika. ʻO nā sila he rubber dissovable a i ʻole plastic.
1.Components o dissovable alahaka plugs
Hana ʻia nā ʻūhā alahaka i hoʻoheheʻe ʻia me ka magnesium-aluminum alloy a i ʻole ka hana polymer material. ʻO ka magnesium-aluminum alloy ka mea nui o ka magnesium, me ka haʻahaʻa haʻahaʻa (e pili ana i 1.8 ~ 2.0g / cm³), a i ka manawa like, he kiʻekiʻe kāna hana kemika, no laila ua maʻalahi ke hoʻoheheʻe ʻia i loko o ke kaiapuni humid.
ʻO ka nui o ka dissolution o ka magnesium-aluminum alloy e pili nui ana i ka mahana wai a me ka Cl-concentration, ʻoi aku ka kiʻekiʻe o ka mahana, ʻoi aku ka wikiwiki o ka hemo; ʻoi aku ka kiʻekiʻe o ka Cl-concentration, ʻoi aku ka wikiwiki o ke kiʻiʻoniʻoni passivation ma ka ʻili o ka alloy e luku, ʻoi aku ka maikaʻi o ka conductivity o ka wai, ʻoi aku ka wikiwiki o ka dissolution rate.
2. Dissovable bridge plug heleuma mekanikini
ʻOkoʻa ka pahu hoʻopaʻa alahaka hoʻokaʻawale mai ka tile hao maʻamau a me ka tile composite, ma kahi o ka pono e hāʻawi i ka ikaika hoʻopaʻa paʻa casing a me ka ikaika paʻa cylinder, akā pono nō hoʻi i ka hana dissolution maikaʻi a me ka hiki ke hoʻi i ka hoʻokuʻu.
3. Dissolvable Bridge Plug Seat Seal Release Value
ʻO Baker 20 # hydraulic noho mea hana e hoʻokuʻu ʻia ke alahaka e noho ana i loko o ka pahu pahu, ʻo ke kaʻina hana hoʻāʻo o ka plug bridge a me ka mea hana noho i hoʻohālikelike ʻia, ua noho maikaʻi ka plug bridge a nalowale ka lima, ka nalowale o ke kaomi lima o 12.3MPa (elike me ka poho o ka lima lima ma kahi o 155kN) noho ka pihi lima e like me ka hoikeia ma ke kii.
4.Pressure sealing hana o dissovable alahaka plug
I mea e hōʻoia ai i ka hana hoʻopaʻa hoʻopaʻa kiʻekiʻe wela o ka plug bridge dissovable, ua hoʻokomo ʻia ka mea hana casing i loko o kahi mea hoʻokolohua wela kiʻekiʻe a hoʻomehana ʻia i 93 ° C. Ma hope o ka paʻa ʻana o ka mahana, ua hoʻonui mālie ʻia ke kaomi i 70 MPa. Ua hoʻopaʻa ʻia ke kaomi no 24 mau hola a laila mālama ʻia no 15 mau minuke. Aia kahi hāʻule paʻi maopopo a hōʻike ʻia ka pihi hoʻāʻo kaomi ma ke kiʻi. Hōʻike nā hopena hoʻāʻo e hiki ke hoʻokō i ka hana hoʻopaʻa paʻa ʻana o ka plug bridge i nā koi o ka hana fracturing ma ka pūnaewele.
5.Working manawa o dissovable alahaka plug
ʻO ka palena manawa hana ʻo ia ka manawa manawa mai ka wā i hoʻokomo ʻia ai ke kaulahao i loko o ka luawai a hiki i ka haki ʻana. Wahi a ke kumu hoʻohālike kūkulu hale shale e kū nei, ʻo ka palena manawa hana o ka plug dissovable bridge plug he 24 mau hola, hiki ke hoʻokō i nā pono o ke kūkulu ʻana i nā pūnāwai shale gas, ʻo ia hoʻi, mai ka manawa i hoʻokomo ʻia ai ka plug dissovable bridge plug. i loko o ka pūnāwai E hoʻomaka ana mai ka hola, hiki ke hana ʻia ke kūkulu ʻia ʻana i loko o 24 mau hola. Hiki ke alakaʻi ʻia kekahi hoʻokolohua hana no nā plug bridge dissovable me ka kuhikuhi ʻana i ka palena manawa hana 24-hola.
